I++ DMS (Dimensional Measurement Services) goals in General:

• Facilitate automated processes and provide services for the exchange of measurement information based on an common data model
• I++ DMS interfaces are of use between participating partners (OEM’s, suppliers) and across the process loop composed from process steps like design, planning, programming, executing and analysis

• Add dimensional inspection and quality-assurance (QA) perspective to model-based process description
• Defines dimensional QA domain-specific terminology and associations between QA relevant model entities
• Describes a complete & coherent description of nominal and actual dimensional data, together with data regarding planning, programming and inspection process steps
• The model can be used in conjunction with MBSE or 3D Master based data models or standalone

• Acceptance by end-users
• Necessary investment in provisions regarding digital process chain and infrastructure (SOAP). This risk can be mitigated be deriving I++ DMS data from existing 2D representations in an automated way
• The standard has currently a high level of acceptance among system providers, but is only actively used by one OEM (BMW).
• Mercedes Benz AG has evaluated the deployment, but will only use the standard if its benefits are in better proportion to the effort required to switch to a service-based infrastructure.
  • This added value is expected from the expansion of the standard by the subject measurement strategies.
